1 Claim. 1

The object of the present invention is to provide a combined table top and frame capable of three operative heights, with the frame and table top so designed that the top may be securely mounted to the frame in each of the three positions, and this quickly and easily accomplished. Thus in my table it may be used as a coffee table for use adjacent a divan or sofa. It can also be converted very quickly to an intermediate height for use as a card table, for example. It may also be quickly converted to full dining table height. This is accomplished without changing the frame in any Way or altering the top.

The invention will be described with reference to the accompanying drawings, in which:

Fig. 1 is a, perspective view showing the table ready for use as a coffee table.

Fig. 2 is a view in side elevation showing the table at its highest position for use as a dining, luncheon or breakfast table.

Fig. 3 is a view of the table, in elevation, showing its position for use as a coffee table, or as shown in Fig. 1.

Fig. 4 is a bottom plan view showing the underface of the table top with the frame in dotted lines and in the intermediate height of the table.

Fig. 5 is a view similar to Fig. 4, with the table of the height shown in Figs. 1 and 3.

Fig. 6 is a view showing the table top with the frame in dotted lines as supporting the top in the position of Fig. 4.

Fig. 7 is a perspective view of the frame.

Referring to the drawings, Fig. 1 shows a table top supported on a frame, the frame being shown in detail in Fig. 7.

The frame consists of two generally rectangular members 2 which may be formed of round or flattened tubing, the said members being connected by spacing struts 3, preferably welded to said members 2.

The characteristic of the table top 4 is that its lower face carries two parallel bars 5 which have exact spacing relatively to members of the frame, and the frame members 2 are so designed as to have exact relationship in their form and spacing to said bars. Each bar is provided with movable rotatable supports 6 or other quickly adjusted engaging members for the frame.

When the frame is turned so that one of the rectangular frame members 2 provides a base or footing for the table, the second frame member 2 provides the lowermost height for receiving the table top I. The longitudinal members of said uppermost frame member 2 will fit outside the space provided by the opposed bars 5, and will abut those bars so that there may be some frictional engagement between said frame members and the bars. It will also be understood that each bar 5 may be so formed at their opposed surfaces, as by a channelway in each of said surfaces, that the top may be mounted on the longitudinal member of the uppermost rectangular frame section 2 by sliding movement. However, in the embodiment shown, which is my preferred form, pivoted straps or catch members 6 will be swung on their pivots for holding the table top to its frame.

When the frame is turned to intermediate height, as in Fig. 7, the reinforcing struts 3 will lie horizontally under the table top, and the frame sections of members 2 immediately connected thereby lie within bars 5 as shown in Fig. 4. Thus the lengths of the struts 3 will be less than the transverse legs of the frame 2, viz. the distance between the longitudinal members of frame 2.

When it is desired to bring the table to its greatest height, the frame is turned from its position in Fig. 7 to its position shown in Fig. 2. In such position the frame will lie within the bars 5 and in abutment therewith.

It will thus be seen that the invention provides a three-height table with no change in the table top or the frame for securing the different heights, and total absence of hinge frame secrelationship; and a metal tubular box-like frame to support said top consisting of two rectangles having relatively long longitudinal and rela tively short transverse sides with the long sides superimposed over one another, and a plurality of at least four spaced apart struts uniting the longitudinal sides of the two rectangles, said struts being of a shorter length than said transverse side, said parallel bars being adapted to exteriorly engage both of the longitudinal sides of a single rectangle as well as to interiorly and alternately engage the opposed sides of the two rectangles, whereby said table has three selectable heights.
